I have been seeing this critter in my tank for about a year and a half now and was finally able to get a decent picture of it. I don't know if it is some kind of worm or a slug? Its underside is flat, kind of like a snail, and it only comes out at night. This picture was taken using the flash with the tank lights off. I have never seen it come all of the way out of its hole, but have seen about four inches of it. Any ideas?
